So, RPS covered a Valve panel that seems to admit, well, Valve has no idea what they're doing with Greenlight
Valve On Steam Greenlight’s Failings, Fixing ThemAs is, then, Greenlight’s less of a magical, crowd-powered game factory and more of an anything-goes gladiatorial arena. Unfortunately, that leaves non-developers like me and probably you in a bit of a tight spot. For normal folks, digging through more than a thousand candidates (and counting) without any rhyme or reason simply isn’t, well, reasonable. As a result, promising games are still bound to slip through the cracks – which is what Valve designed Greenlight to avoid in the first place.
...
Right now, Valve fully admits that it doesn’t have an answer.
And I agree with this nattering nabob of negativity comment in the thread there:
The whole Community Update has been a complete mess. The lack of proper moderating tools (and mods for that matter) in the Discussions pages, the insane amount of notification spam, the shitty social network-wannabe page layouts, and the fact that the update seems to have attracted a whole new level of Facebook-like stupidity were all the final nail in the coffin for me.
I no longer participate in the Steam community because taking part feels like nothing more than an unnecessary headache now.
I used to actively post in the Steam forums on many games but basically there are too many forums, mostly completely unmoderated at all (you might as well be on unmoderated USENET newsgroups). It's ugly and I don't want to hang out there anymore, not even just to check feedback on new games.
imho, Steam is wasting waaaaay too much time/resources emulating social media and crowd-funding and whatever's Trendy This Week. I'm sure we'll have "MySteam" pages and "SteamBook" gathering sites to go with "SteamStarter" funding donation pages. Perhaps to go with the "Steamify" streaming randomized game service, and so on....
Not to mention pelting us all with tab after tab after tab of Click Here and Click This and Join This and Tell Your Friends' Friends' Friends' Enemies what you thought of this game stuff.
None of this is preventing me from buying games on Steam (bought Borderlands 2 and Torchlight 2 on it, and pre-ordered XCOM), but more and more I just want to play my games and chat a bit with Steam friends and ignore all the bloat that Steam is determined to cram in, much of what are lost on me (and apparently others).
